## Prize Title
Image Encryption in Maskbook
## Prize Bounty
1000 DAI
## Challenge Description
Maskbook is a browser extension that enables users to create encrypted posts on Facebook and Twitter(so far, more to come!). This has been running for almost a year and we want to extend it functionality in this challenge. We only support text post encryption, which encrypts plaintext with an **AES** key in **GCM** mode and shares the **AES** key **securely** with the designated recipients with **ECIES**. We also support an **image mode** that embeds the ciphertext in an image with the technique of steganography.
You can try it out by installing our extension on [Chrome](https://chrome.google.com/webstore/detail/maskbook/jkoeaghipilijlahjplgbfiocjhldnap) or [Firefox](https://addons.mozilla.org/en-US/firefox/addon/maskbook/).
In this challenge, we want more. We want to further help users share their photos privately, without being monitored by the platforms. The mission is pretty straightforward: all you need to do is to add another portal in our extension to support image uploading, or even dragging to upload. And then encrypt them efficiently, paste in the draft editor and share the symmetric encryption key securely just as is in our text mode. We would like a fully functional image encryption scheme and it shouldn't depend on or conflict with our mainstream.

## Contact & Support
Feel free to open an issue in our repo or directly reply to this thread. You can also reach us at https://gitter.im/Maskbook/community but we barely use it. We mainly use a self-deployed [Rocket.Chat](https://dimension.chat) in our team development but its registration is hidden. We will send the registration links to the participating teams/developers once confirmed.
